vTo all may concern;

zen' of the United States, residing atLa Porte, in the county of La Porte an'd State of Indiana, have inventeda certain new. and

and Assemblies, of which the following is, a specification.

This invention relates to the construction of afradiator and the exhaust arrangement.

of an internal combustion tractor and particularly to the combination of the twowhereby the exhaust is satisfactorily muflled and whereby the power from the. exhaust is utilized to draw air through the radiator. It has for one object the combination of a radiator with an exhaust to assist in the passage of air through'theradiator. It has for another object to mufiie the exhaust. Other objects will appear from time to time throughout the'specificatlon and claims.

My invention is illustrated more or less' diagrammatically in the accompanying drawings, wherein:

Figure 1- is a side elevation of the'radiator assemblywith parts broken away Figure 2 is a front elevation of the same; "Figure 3 is a plan view; I Figure"4- is a plan view of the exhaust nozzle on an enlarged scale with parts broken away; g

Figure 5 is a vertical cross section of the I same with parts'broken away.

Like parts are designated by like characters throughout.

.A is a radiator housing, open'at its bottom, in which the radiator B, of which the front section is partially shown, is ositioned. There is here shown a radiator which is built up of a plurality of vertical sections, spaces being left between each section. A radiator of almost any other type might, however, be used in this connection. The details of the radiator will not here be described as they form no part of the present invention. The radiator sections are tied together .b heads G C are ere shown. The discharge connection for the fluid is here shown as at C thesupply connection being omitted.

The top of the radiator housing is closed by a hood I) which terminates in the flared funnel D. This funnel is circular in cross section and flared outwardly as shown. .VVithin the hood D and above the radiator is bolts of which only the.

g positioned the exhaust-nozzle E. As shown Be it known that- I, JOHN A. Snoo'n, a cit1-' the .nozzle comprises an annular channel E providedabout it's topwithan annular opening E Communicating with this annular channel is a tubular section of the nozzle which is' provided with twobranches E E. In the form here shown thenozzle is adapted primarily for use with a two cylinder engine. Each of the cylinders is connected o one of the passages, E5 E This arrangement obviously might be varied. There' might be more than two passages E or'there might beibut one. At one'side the nozzle is provided with the laterally extending ears E E by means of which' it is supported upon and secured to the framework of the radiator casing. At its opposite side it is provided with the arm E which is a1so7supported from-and secured to the framework of the radiator casing.

Although I have shown anoperative device, still itwill be obvious that many changes in form, shapeand arrangementof I parts may be made'without departing materially from the spirit of my invention, and

as in a sense diagrammatic.

As appears particularly in Figure '5 there is provided in the annulus a depression in line with the incoming gases. The depression is adaptedto collect Water which may be carried with the gases or condensed out from them. It is provided with a perfora tion so that Watermaybe discharged and the annulus kept at all times substantially theengine are connected to the exhaust nozzle so that burned gases from the cylinders are exhausted into the nozzle. shownis connected with the cooling jackets of" the engine and the cooling fluid is circulated through the radiator. The casing owing it The radiator II .wish therefore that my showing be taken which encloses the radiator is open at the bottom and at the to When the engine is in operation, burne' into the tubular part of the exhaust nozzle and because of their. force they tend to rush about the annular portion of the nozzle. As above noted the particular arrangement here shown is intended to be combined with j a two cylinder engine, the cylinders operat- 10 ing alternately so that first one will exhaust and the gases will be discharged into the nozzle and will rush about the annular por- .-tion of .it and then the other cylinder will discharge and its gases will rush about the opposite sidevof the annular'portio'n and in the opposite direction. In this operation the force of each exhaust charge is, practically expended before the gases have made a complete circuit of the annular portion of the exhaust nozzle. Since the annular portion of the nozzle is open about its upper side,

- the moment the gases strike it some of them escape upward, and it is this upward escape of the exhaust gases which to a considerable extent serve to diminish their velocity. The velocity of the exhaust gases is thus largely diminished and the noise, of the exhaust is mufiled.

The arrangement shown, however, has an additional. purpose. Since the exhaust gases are discharged upward from out the annular portion of the nozzle and since the radiator casing is open both at its top and its bottom the exhaust'gases set up a currentof air,

exhaust gases-greatly increases the flow of gases are exhausted air, and thus very greatly multiplies the quantity of air which will pass through the radiatorin a given time and so serves to improve its cooling qualities.

1 he hood over the top of the radiator casing serves to constrict to some extent the passage through which the air must 4 pass. It is to be noted that the upper edge of the passage where it joins the lower edge of the funnel is larger in diameter than the annular openingfin the top of-the exhaust nozzle and that it is situated above the exhaust nozzle and that the upper edge of the funnel is flared outwardly from its lower edge. This combination greatly improves the action of the assembly and increases the amount of air which is drawn through the radiator and the radiator casing. This ef fectis in some measure due to the modified venturi which is formed by the arrangement of the parts just described.

I claim:

1. As a new article of manufacture an engine muflier, said mufller being generally annular in shape and provided with an annular exhaust opening, an exhaust impulse balancing means comprising a plurality of oppositely directed separate exhaust connections communicating with said mufiler whereby exhaust discharges are directed in opposite directions to balance each other.

2. In combination with an internal combustion engine a mufller shaped generally in the form of an annulus and provided withan annular-exhaust opening, and provided also with exhaust impulse balancingmeans comprising a plurality of oppositely directed exhaust connections communicating with the interior of said muffler whereby successive exhaust discharges are directed in opposite directions about said annulus and balance each other. v
